Bonding and Grounding When Dispensing Flammable Liquids

Are flammable liquids being dispensed at your facility?  If so, are proper bonding and grounding procedures in place?

OSHA’s requirements for bonding and grounding of flammable liquids can be found in 29 CFR 1910.106.  More specifically, 1910.106(e)(6)(ii) states that all Category 1 or 2 flammable liquids (as defined in this standard), or Category 3 flammable liquids with a flashpoint less than 100 degrees Fahrenheit, shall not be dispensed into containers unless the nozzle and container are electrically interconnected.  NFPA 77, Recommended Practice on Static Electricity, also provides recommendations for bonding and grounding practices.

If you have equipment that is generating flammable waste into drums, make sure that the drums are properly grounded.  If flammables are being dispensed from drums or cans into smaller containers, make sure that the source container is grounded, and the two containers are bonded by a bonding wire.  Hazardous waste storage rooms where waste is being consolidated from satellite accumulation area containers into 55-gallon drums must be equipped with a grounding bar to ground the drums.  When connecting bonding and grounding wires to a steel drum, make sure the connection is established by removing the paint under the clamp at the connection location.

Be sure to avoid incidents resulting from the buildup on static electricity by implementing appropriate bonding and grounding procedures.
